Abstract
The present disclosure relates to a composition, comprising a monomer; a reactive co-stabilizer; a carbon black; a surfactant; and a filler, wherein the composition is used to prepare a polymer/carbon black composite particle by MEP technology along with a method for same. The reactive co-stabilizer as disclosed is methacrylate derivative containing a long alkyl chain R, with R consisting of 6-22 C atoms and being branched or linear, saturated and/or unsaturated such as stearyl methacrylate (SteaMA). The polymer/carbon black composite particle as prepared has an enhanced stability and low VOC as compared to a pure polymer prepared by MEP. Further, the prepared polymer can be used as basic resins in materials for toner applications.
